Java 刷新时未更新图像

java android

Java 刷新时未更新图像,java,android,Java,Android,我是新来的。所以我才开始探索android。更具体地说是关于图像。现在我正在尝试毕加索图书馆。我的问题是，当我使用毕加索时，我上传到数据库的新图像没有在imageView（2.PreviewImage.java）上更新。在高级中执行帮助和TQM。仅供参考。将图像上载到数据库时没有问题 1.MainActivity.java EditText editText; Button button; @Override protected void onCreate(Bundle savedInstan
